名称

count_objcount_objCountObjCountObjcount_obj — 元组中的对象数。

签名

count_obj(Objects : : : Number)

描述

算子 count_objcount_objCountObjCountObjCountObjcount_obj determines for the object parameter ObjectsObjectsObjectsObjectsobjectsobjects the number of objects it contains. In this connection it should be noted that object is not the same as connection component (see connectionconnectionConnectionConnectionConnectionconnection). For example, the number of objects of one region consisting of three parts that are not connected is 1.
